I don't believe any patches will make this game suited for me. I am already reconciled with fact that game is not my cup of tea and it does not mean there is something wrong with game or me.
But If it was up to me how to change the game, here is my wishlist:
Of course hitboxes mess takes priority to fix. It's probably obvious to everyone
It will sound vague but I want characters to feel more complete. I tried in this game Kitana, Cassie, Skarlet, Jade, Johnny, Kung Lao and Geras. Even though it's basically whole tier list spectrum only one character from those felt complete. It's Geras. Every other character - even the top tier and good ones like Cassie, Jade and Skarlet - felt half finished and I ended up using the same tools over and over because how much stronger they were compared to others. For example Kitana is filled with strings like 21222 21343, 32 which you will never use. Why would you throw out this short range slow 13f highs when you have 13f mid with better range than leaves you less negative on block?
Nerf pokes. 6-7 frame pokes that have good range and are -2, -3 or -4 on block has to go. If your character have bad pokes and does not have 9f hit confirmable mid playing vs Errons, Shangs, Scorpions and Gerases feels absurd. It's super frustrating when oponnents just throw pokes on block like machingun. And you can't enforce your turn back or even poke back. Every time Scorpion does D1 into D1 on block and it works part of me dies. Also pokes should universall jail into highs on hit.
Fatal blow needs total rework. In some matchups game literally punishes you for heaving a life lead. Many times when you have a life lead, but it's not that big that you cannot allow yourself for just taking fatal blow, characters like Erron Black or Jax puts you in huge disadvantage. You are automatically using neutral from anywhere on screen and game is gone and you sudenly need play around full screen, armored unreactable threat. In my opinion fatal blow cooldown has to go. You can't have fatal blow back if you missed it. I don't know how many krushing blow has requirement that moves has to connect during fatal blow cooldown (I know that one of Kitana's custom move has requirement like this) but those requirement needs to be changed. Also all fullscreen fatal blows has to have decreased range or increased starup so you can see them.
I would make jump kicks negative on block. Wanna have pressure after jumpins? Use jump punches which are universally easier to anti air.
